Definitions
- the invention relates to a seat monitoring system for monitoring the status of at least one seat that can be arranged in an interior of a vehicle and for determining the position of the seat in the interior, as well as a method for determining the position, the seat monitoring system being particularly characterized in that it has exactly two antennas on the vehicle and on the seat for monitoring and determining the position be used.
- all seats should be removed from a vehicle for goods transport, all seats or at least some seats should be installed in the vehicle for passenger transport and existing seats should be different depending on the situation, e.g. B. rotated, can be arranged.
- a seat monitoring system is known from DE 102008 031 494 B4, which determines a distance between a transmitter and the receiver from a single signal strength and by comparing the determined distance with the distances between the transmitter and several predetermined areas in which a seat can be arranged , in which of the predetermined areas the seat is arranged.
- DE 11 2017 005 187 T5 proposes a seat monitoring system which is designed to determine a position of the seat by determining the distances from the seat to exactly three transmitters (antennas).
- the seats or seat modules provided on the seats transmit status values, such as a status of the seat belt, ie whether it is fastened or open, to a control module provided in the vehicle.
- this requires a sensor module in or on the seats, which records these status values.
- the object of the invention is to provide an alternative system for seat monitoring, which provides another option for determining the position of the seat in the vehicle.
- a seat monitoring system for monitoring a state of at least one seat that can be arranged in an interior of a vehicle and for determining the position of the seat in the interior.
- the seat monitoring system can be provided, for example, exclusively in the rear of a vehicle or also in the entire interior.
- the seat monitoring system has a control module, precisely two transmitter modules connected to the control module for signaling purposes, and at least one seat module.
- the at least one seat module is assigned to at least one seat, for example two or more seats can also be connected to form a unit, so that the seat module can be assigned to the unit of seats.
- the at least one seat module or each seat module has a receiving module and in particular precisely one receiving module.
- the invention is characterized in that the Exactly two transmission modules are arranged at a distance from one another and each have exactly one antenna.
- the receiving module also has exactly two antennas, with a first antenna of the exactly two antennas of the receiving module being designed to receive a signal from a first transmitting module of the exactly two transmitting modules or exactly one antenna of the first transmitting module, and with a second antenna of the exactly two antennas of the receiving module is designed to receive a signal from a second transmitting module of the exactly two transmitting modules or exactly one antenna of the second transmitting module.
- the receiving module is designed to measure signal strengths (RSSI) of the signals received by the antennas of the receiving module, ie a first signal strength of the signal received by the first antenna of the receiving module by the antenna of the first transmitting module and a second signal strength of the signal received by the second antenna of the receiving module the antenna of the second transmitter module received signal to determine the position.
- RSSI signal strengths
- the first antenna of the receiving module is preferably designed, for example by means of a corresponding alignment and/or signal filter, to receive and/or evaluate exclusively the signal of the antenna of the first transmitting module.
- the second antenna of the receiving module is designed, for example by a corresponding orientation and/or signal filter, to receive and/or evaluate exclusively the signal of the antenna of the second transmitting module.
- the receiving module is connected to the control module in terms of signals and is designed to send data to the control module.
- the receiving module can also be designed to receive digital information and/or digital data and more particularly the information as to whether the seat module is inside space or as far as an area in the interior is determined, in which the seats can be arranged, whether the seat module is arranged in the area to send to the control module. Whether the seat module is arranged in the interior or in the area can be determined, for example, by the fact that the receiving module has received a signal from each of the two transmitting modules. For example, if a signal is received by only one of the receiving modules, the information that the seat module is not arranged within the vehicle or the area can be sent to the control module.
- the signaling connection can be established, for example, by a bidirectional radio link via the antennas of the receiving module and the respective antenna of the transmitting modules. It is also possible that only one radio connection between exactly one antenna of the receiving module and exactly one transmission module is bidirectional and the other radio connection is unidirectional.
- the exactly two antennas of the receiving module can be LF antennas and an additional antenna of the seat module, which can also be provided outside of the receiving module, can be an HF antenna.
- the antennas of the transmission modules are also designed as LF antennas and an additional antenna connected to the control module for signaling purposes is designed as an HF antenna. Since neither the additional antenna of the seat module nor the additional antenna connected to the control module is used to determine the position, their arrangement in the vehicle is arbitrary and independent of the other antennas.
- the transmission modules and, if present, an additional antenna are preferably connected to the control module in terms of signals by cable or wire.
- control module and the transmission modules can be fixed at a fixed, unchangeable position in the vehicle and are therefore assigned to the vehicle, and that the seat module is assigned to at least one seat and is arranged with the seat in the vehicle or removed from the vehicle.
- the receiving module is designed to transmit the signal strengths of the signals received by the antennas of the receiving module to the control module for position determination.
- the receiving module is designed to transmit a position of the seat in the interior of the vehicle to the control module. The position can then be determined by the seat module from the signal strengths of the signals received by the antennas of the receiving module.
- the receiving module is designed to transmit a digital signal, in particular, containing status values to the control module.
- a condition value of the belt that can be described as a belt value, an occupancy value (seat occupied, seat not occupied, seat occupied with a child seat), a load value (force acting on a seat surface of the seat), an inclination value (inclination the seat surface and/or the backrest of the seat), a headrest value (headrest present, not present) and other values relating to the seat.
- a seat module can also be assigned to a number of seats and accordingly a number of similar status values can be recorded and/or transmitted. For example, to determine such a state value, several such state values or also to determine similar state values of several seats, it can be provided that the at least one seat module has a sensor module which is designed to determine state values of the at least one seat to which the seat module is assigned.
- the antennas of exactly two transmission modules and/or exactly two antennas of the reception module are unidirectional antennas, i.e. antennas that only transmit data in one direction.
- the antennas of the exactly two transmission modules and/or the exactly two antennas of the reception module are one-dimensional transmitting and/or receiving antennas, where one-dimensional is understood to mean that the antennas are designed to transmit signals essentially only in send or receive a direction in space.
- the at least one seat can be arranged in a predetermined and in particular rectangular area in the interior of the vehicle and the respective position of exactly two transmitter modules relative to the area is known and cannot be changed in relation to the area. Determining the distances between the seat module and the transmitter modules results in two intersection points of circles around the transmitter modules with the respective distance as a radius when viewed in one plane. If an intersection lies outside of the predetermined range, this point can immediately be ruled out as the position of the seat or it can be concluded that the intersection lying within the range corresponds to the position of the seat or the seat module.
- this results in the respective predetermined position of the transmission modules is selected relative to the area in such a way that two intersection points of all possible circles, the center of which is one of the transmission modules, in each case one intersection point lies within the area and one intersection point lies outside the area.
- the first transmission module is arranged along a first axis and the second transmission module is arranged along a second axis that is inclined relative to the first axis.
- the first axis and the second axis are orthogonal to each other.
- the axes can, for example, delimit the area or be arranged outside the area.
- the at least one seat has a seat base for releasably fixing the seat in the vehicle as an interface to the vehicle.
- the seat module also has a predetermined and stationary position relative to the seat base, so that the seat module of a seat arranged in the area is arranged in a predetermined plane. If the module that carries out the position determination, i.e.
- the seat module and/or the control module knows this relative position of the seat module to the seat base or the level and the positions of the transmitter modules, the position of the seat module relative to the transmitter modules can be determined more precisely because a possible difference between the position of the transmitter module and the position of the seat module along the vertical axis of the vehicle can be taken into account.
- the at least one seat is attached to a predetermined mechanical latching point.
- ten grid and/or can be arranged or detachably fixed in the area on at least one rail aligned with the predetermined grid.
- This grid and/or possibly the course of the at least one rail on the grid can also be taken into account when determining a position in order to be able to determine the position with greater accuracy and at the same time to be able to determine additional information.
- the at least one seat module and/or the control module is preferably designed to determine a respective distance of the at least one seat module from the transmitter modules from the signal strengths of the signals received by the antennas of the receiver module and to determine the position of the seat module in the vehicle from the distances.
- the at least one seat module and/or the control module is formed from the signal strengths received by the antennas of the receiver module Signals a respective distance of the at least one seat module to the transmitter modules and from the distances and from the predetermined grid to determine the position of the seat module and in particular an orientation of the seat assigned to the seat module in the vehicle, with additional information from a deviation of a position of the seat module from the grid can be determined.
- the associated seat is arranged at the resting point or on the rail. If it is assumed that the position determined on the basis of the signal strength is sufficiently precise, a rotation and/or orientation of the seat about the locking point can be determined from a deviation from a (nearest and therefore associated) locking point.
- a seat module is assigned to exactly one seat and arranged on the seat in such a way that it always lies at a locking point, it can be assumed that the seat module is assigned to exactly one seat if the position is determined from the signal strength and is at a locking point. If, for example, another seat module is assigned to exactly two seats and arranged on the two seats in such a way that it is always offset by a previously known offset from a rest point, a position determined from the signal strength and the resulting offset to the nearest rest point can be used be assumed that the seat module is assigned to two seats and whether the seats are aligned, for example, to the front of the vehicle or to the rear of the vehicle. No additional sensors are required for this, since these values, understood as status values, can be determined directly from a deviation of the determined position from the grid.
- the driver's seat can be permanently mounted in the interior.
- the driver's seat can also be arranged within the area and have a seat module, so that the position determination can be calibrated with the seat module assigned to it based on the previously known and fixed position of the driver's seat.
- a further aspect of the invention relates to a method for determining a position of a seat in an interior of a vehicle with a seat monitoring system according to the invention. It is provided that from a first distance of the seat module from the first transmitter module and a second distance of the seat module from the second transmitter module is calculated from the signal strengths (RSSI) of the signals received by the exactly two antennas of the receiver module. Possible positions of the seat module, in particular those lying in a predetermined plane, are then determined from the first distance and the second distance. If more than one position is possible, non-possible positions can be excluded or a single correct position can be concluded by taking additional information into account. A position within the vehicle is understood as the correct or the only correct position.
- RSSI signal strengths
- a determination of the actual position is possible by taking into account a predetermined area in which the seats can be arranged. Additionally or alternatively, a grid on which the seats can be arranged can be taken into account. In addition or as an alternative, a predetermined transmission direction of the antennas of the transmission modules and/or a predetermined reception direction of the antennas of the reception module can also be taken into account.
- FIG. 1 shows a seat monitoring system in a first seat arrangement
- FIG. 2 shows a seat monitoring system in a simplified representation.
- FIGS. 1 and 2 each show a seat monitoring system 1 for monitoring the state of at least one seat 2 that can be arranged in an interior and more precisely in an area 30 in the interior of a vehicle and for determining the position of the seat 2 in the interior or in the area 30.
- 1 corresponds to a top view of a possible seat monitoring system 1 and FIG. 2 to a more schematic depiction of a seat monitoring system 1, which can also be the seat monitoring system 1 according to FIG.
- the seat monitoring system 1 has a control module 10 integrated into the vehicle and exactly two transmission modules 11 , 12 connected to the control module 10 for signaling purposes, for example via a physical line 17 .
- the transmission modules 11 , 12 are stationarily arranged in relation to the area 30 at a predetermined position and in the present case along an axis X, Y which delimits the rectangular area 30 and is arranged orthogonally to one another.
- the seat monitoring system 1 also has at least one seat module 20, the number of seat modules 20 corresponding to the number of seats 2 arranged in the vehicle or the number of seat units 200, which can be formed from a plurality of seats 2.
- each seat module 20 is assigned to at least one seat 2 .
- a seat module 20 is associated with a seat unit or seat group 200 of two seats 2 connected to one another.
- Each seat module 20 also has a receiving module 21, as shown in FIG. Exactly two transmission modules 11, 12 are arranged at a distance from one another and each have exactly one antenna 13, 14 shown in FIG.
- Each receiving module 21 of each seat module 20 also has exactly two antennas 23, 24, with a first antenna 23 of the receiving module 21 is designed to receive a signal from a first transmission module 11 of exactly two transmission modules 11 , 12 , and a second antenna 24 of reception module 21 is designed to receive a signal from a second transmission module 12 of exactly two transmission modules 11 , 12 .
- the receiving module 21 is designed to determine signal strengths of the signals received by the antennas 23, 24 of the receiving module 21 for position determination.
- the distance A1, A2 of the receiving module 21 from the two transmitting modules 11, 12 can be determined from the signal strengths (RSSI). Since the receiving module 21 or the seat module 20 cannot be located anywhere in the room, but is always arranged in a certain plane, which runs parallel to the floor of the vehicle, for example, two possible positions of the seat module 20 relative to the transmitter modules can be determined from the distances 11, 12 can be closed.
- RSSI signal strengths
- a first distance A1 corresponds to the distance between the receiving module 21 and the first transmitting module 11 in the plane
- a second distance A2 corresponds to the distance between the receiving module 21 and the second transmitting module 12 in the plane.
- one of the two intersections S1, S2 is within the area 30 and the other intersection is outside of the area 30, so that it can be directly concluded that the within the area 30 lying intersection of the position of the seat module 20 corresponds.
- Such a conversion can also be supplemented by a grid 34 on which the seats 2 can be arranged, in order to increase the accuracy of the position or to obtain additional information about the seat 2 .
- the seats 2 or the seat units are mechanically fixed in the vehicle and a grid is provided in the vehicle for this purpose, which grid can have latching points or latching rails, for example.
- this deviation can be determined and further information can be generated from it.
- the seat module 20 is arranged centrally in the seat unit 200 in the vertical direction, as shown. Accordingly, the position of the seat module 20 of the seat unit 200 lies precisely between two horizontally extending locking planes 341 of the grid 34 and not, as is the case with individual seats 2, exactly on a horizontally extending locking plane 341 of the grid 34, so that the position can be used to determine directly that it is is not a seat module 20 of an individual seat 2, but a seat module 20 of a seat unit 200.
- the determination of the distances A1, A2 and the determination of the position of the seat module 20 can be carried out by the seat module 20 itself and, for example, by a corresponding computing unit 26 of the seat module 20.
- the position determined in this way can then be sent to the control module 10 via a return channel.
- the return channel can take place via a separate radio connection 15 for unidirectional or bidirectional data transmission, for which purpose the seat module 20 can have an HF antenna 25, for example.
- the distances A1, A2 or just the signal strengths can be sent from the seat module 20 to the control module 10 and the position of the seat module 20 can be determined by the control module.
- control module 10 can have an interface 16 for data transmission to other control devices of the vehicle or can be connected to them via CAN-BUS.
